Question

7/15 + 9/16 + 8/15 + 7/16

Answer 1

bài này dễ mà chịu khó tính một chút là được ahihi..................

Answer 2

\(\frac{7}{15}+\frac{9}{16}+\frac{8}{15}+\frac{7}{16}=\frac{7}{15}+\frac{8}{15}+\frac{9}{16}+\frac{7}{16}=\frac{15}{15}+\frac{16}{16}=1+1=2\)

Answer 3

( 7/15 + 8/15 ) + ( 7/16 + 9/16 )

= 15/15            +        16/16

=     1               +            1

=                      2

Answer 4

\(\frac{7}{15}+\frac{9}{16}+\frac{8}{15}+\frac{7}{16}\)

\(=(\frac{7}{15}+\frac{8}{15})+(\frac{9}{16}+\frac{7}{16})\)

\(= \frac{15}{15}+\frac{16}{16}\)

= \(1+1\)

\(=2\)

Answer 5

\(\frac{7}{15}+\frac{9}{16}+\frac{8}{15}+\frac{7}{16}\)

\(=\left(\frac{7}{15}+\frac{8}{15}\right)+\left(\frac{9}{16}+\frac{7}{16}\right)\)

\(=1+1\)

\(=2\)

Answer 6

7/15 + 9/16 + 8/15 + 7/16 = 2 <OK!!!>

Answer 7

\(\frac{7}{15}\)+ \(\frac{9}{16}\)+\(\frac{8}{15}\)+ \(\frac{7}{16}\)

= \(\left(\frac{7}{15}+\frac{8}{15}\right)\)+ \(\left(\frac{9}{16}+\frac{7}{16}\right)\)

= 1 + 1

= 2

Answer 8

\(=\left(\frac{7}{15}+\frac{8}{15}\right)+\left(\frac{9}{16}+\frac{7}{16}\right)\)

\(=1+1\)

\(=2\)

Answer 9

7/15+8/15=15/15=1

9/16+7/16=16/16=1

1+1=2

2 bạn nhé

k cho mk nhé

Answer 10

\(\frac{7}{15}+\frac{9}{16}+\frac{8}{15}+\frac{7}{16}\)

\(=\left(\frac{7}{15}+\frac{8}{15}\right)+\left(\frac{9}{16}+\frac{7}{16}\right)\)

\(=1+1\)

\(=2\)

Answer 11

\(\frac{7}{15}+\frac{9}{16}+\frac{8}{15}+\frac{7}{16}\)

\(=\left(\frac{7}{15}+\frac{8}{15}\right)+\left(\frac{9}{16}+\frac{7}{16}\right)\)

\(=\frac{15}{15}+\frac{16}{16}\)

\(=1+1=2\)
